Welcome

Congratulations on your purchase of a Honeywell Home touch screen programmable thermostat. When used with the optional RedLINK Internet Gateway, you can remotely monitor and control the heating and cooling system in your home or business—you can stay connected to your comfort system wherever you go.
The Total Connect Comfort app is the perfect solution if you travel frequently, own a vacation home, a business or manage an investment property or if you are simply looking for peace of mind.

Features of your VisionPRO thermostat

With your new thermostat, you can:

Connect to the internet to monitor and control your heating/cooling system and receive alerts by email (requires optional RedLINK Internet Gateway)
View outdoor temperature and humidity (requires optional Wireless Outdoor Sensor)
Control humidification, dehumidification, or ventilation (TH8321 model)

Your new thermostat also provides:

Adaptive Intelligent Recovery—over time, the VisionPRO thermostat “learns” how long it takes your system to reach the temperature you want. It turns on the heating or cooling system earlier to make sure you’re comfortable at the time you expect.
Dealer information on the screen—making it easy for you to contact your dealer for service.
Vacation and holiday schedule—allowing you to program a setback temperature to save energy while you are away.
Keypad lockout to prevent unauthorized changes.

Replacing thermostat batteries

Install fresh batteries when the REPLACE BATTERIES warning begins flashing. The warning flashes about 60 days before batteries are depleted.
Even if the warning does not appear, it is recommended to replace batteries once a year, or before leaving home for more than a month.
Press the release button on top of the thermostat to remove it from the wall plate.
Some versions of this thermostat don’t have a button on the top.
In that case, grip the thermostat along the top and bottom and pull it straight off the wallplate.
There is also a CR2032 coin cell battery located on the back of the thermostat.

Replacing outdoor sensor batteries

Replace batteries in your outdoor sensor when a warning appears on the thermostat screen, about 60 days before batteries are depleted.
To replace the batteries:

Remove the sensor from the bracket.
Detach cover.
Install 2 fresh AA lithium batteries.
Replace the cover and set the sensor back into the bracket.

The outdoor sensor will restore communication with the thermostat a few seconds after new batteries are installed.

Replacing indoor sensor batteries

Replace batteries in your indoor sensor when a warning appears on the thermostat screen, about 60 days before batteries are depleted. When the sensor status light begins flashing red, battery power is critically low and will be depleted within 2–3 weeks. During normal operation, the status light remains off.
To replace the batteries:

Remove the sensor from the wallplate.
Install 2 fresh AAA alkaline batteries. If the status light flashes green, batteries are good; if it flashes red, you must use fresh batteries.
Attach sensor to wallplate.

The sensor will restore communication with the thermostat a few seconds after new batteries are installed.

Using the temperature display

In some circumstances, the temperature displayed on the Home screen may not match the temperature near the thermostat. If your system is set up to use remote indoor ensors, it may be reading a sensor in another location.

Using the humidity display*

In some circumstances, the humidity displayed on the Home screen may not match humidity near the thermostat.
Some systems are set up to use two sensors, one to control humidification, the other for dehumidification. These sensors are often installed in different locations.
Depending on how your thermostat was installed, the thermostat Home screen will display humidity readings from only one sensor.
* Indoor humidity is not displayed on TH8110R and TH8320R models that are not used with a wireless indoor sensor

Optional accessories

Troubleshooting

If you have difficulty with your thermostat, try these suggestions. Most problems can be corrected quickly and easily.

Screen is blank	• Check the circuit breaker and reset if necessary. • Make sure the power switch at the heating and cooling system is on. • Make sure the furnace door is closed securely. • If the thermostat is battery powered, make sure fresh AA alkaline batteries are installed correctly (see page 16).
The screen is difficult to read	• Change screen brightness using the Preferences menu (see page 13).
The red light is on	• If the thermostat is in Emergency Heat mode, the red light is normal. It shows that the thermostat is in Emergency Heat mode. • If the thermostat is not in Emergency Heat mode, an alert is active. Check the message on the thermostat screen.
The heating or cooling system does not respond	• Touch SYSTEM to set the system to Heat. Make sure the temperature is set higher than the Inside temperature. • Touch SYSTEM to set the system to Cool. Make sure the temperature is set lower than the Inside temperature. • Check the circuit breaker and reset if necessary. • Make sure the power switch at the heating & cooling system is on. • Make sure the furnace door is closed securely. • If “Wait” is displayed, the compressor protection timer is on. Wait 5 minutes for the system to restart safely, without damaging the compressor.
Cannot change time or date	• See page 3. If the thermostat doesn’t allow you to adjust time/date and is used with a RedLINK Internet Gateway, the thermostat is getting the time/date information from the address entered under the location that the thermostat is registered to in the Total Connect Comfort account. If the thermostat is newly installed without a gateway, there can be a 72-hour delay before the thermostat will allow you to set a time and date. To bypass the delay, remove the thermostat from the wall plate (see page 16) and remove the coin cell battery for at least one minute. Then put the battery back in and re-attach the thermostat to the wall plate.

Quick Start Guide

does this thermostat requires “C” wire?

In an HVAC system there is a step-down transformer that takes the 240VAC or 120VAC and steps it down to 24VAC. The primary side of the 24VAC is what has always been connected the R terminal of a thermostat. The secondary side of the 24VAC transformer was not. It is this secondary side of the 24VAC that is needed by newer thermostats. In fact the newer thermostats are powered by the 24VAC. That secondary side is what is connected to the C terminal. If your cable has a spare unconnected wire. It could be connected to the secondary of the transformer and then to the C terminal. To see if it is there but but not connected, us a VOM and set for AC Voltage, put one lead on the R terminal, and the second lead to each unconnected wire(s), one at a time. if it shows 24VAC +/- 4VAC, you found the secondary side. All other wires will show OC or open. That secondary side wire is the C wire

How does this sense the outside temp and humidity?

It does show the inside humidity and you can look at the app side and see the outside temp based on internet lookup of temp but there are no sensors for exterior temp or humidity. Just some additional clarification if it helps.

Will adding a fossil fuel kit allow me to use this thermostat in a dual-fuel (heat-pump/gas furnace) system?

Yes; by adding a fossil fuel kit you can use this thermostat in a dual-fuel system.

Is this a T10 thermostat?

The RTH9585WF is not a T10 thermostat. Just in case you need it, the T10 thermostat product number is THX321WFS2001W/U.

Where do you install batteries?

this thermostat doesn’t work on batteries. This model requires a C wire for power.

Does this require any special wiring or equipment to install?

This thermostat requires a C wire for power.

Will this work in UAE?

If you have US type HVAC air conditioning system with remote thermostat(s) in the UAE – perhaps this will work. It is not usable with typical split and multi-split AC units that are most common in middle east and across Asia (but increasingly across the southern USA).
The remote used with splits sold by Daikin, York, Gree, Samsung, LG, Panasonic, etc is used to adjust the the temperature of the internal thermostat within the split indoor “evaporator” head.

Will this work on a dual fuel system?

No it will not.

how do you release the wires from the terminal strip?

to remove the wires from the thermostat wall plate you have to press and hold the circle cleft on the terminal tab next to the terminal letter while pulling out the wire.
